Why Grandparentage Testing?

Grandparents seek
DNA testing on their grandchildren for either of two
common reasons: they have doubts about the paternity
of their son's or daughter's child, or they would like
to prove that they are related to a grandchild whose
family denies the relationship and bars them from developing
a relationship with the child (Read
more about these situations.) With a DNA grandparentage test, you can
conclusively determine if a child is your biological
grandchild or not.

Grandparentage
testing is usually performed when the possible
father is not available for a DNA
paternity test. In such cases, we can test the biological parents of the possible father and compare their DNA with the child's
DNA to see if the possible grandparents have passed down
their genetic material to the child through the
father. Conversely, we can also test for maternal
grandparentage to confirm biological relationships
in situations where a mother and child were separated
early in life, but the mother is no longer available
for a maternity test.

Can I do this at home?

Grandparentage testing can be
done privately, with those being tested collecting
samples themselves, in the privacy of their own home. The results of
this test are for personal knowledge only and cannot be used as evidence
in a legal proceeding, such as child custody. A chain-of-custody
grandparentage test, which can be used in court, requires tested
parties to have their samples collected by a trained professional, usually
at a clinic or laboratory.

Stories

Wanting
to be sure...

"My grandson looks nothing like my son, and
I know his mother has not always been faithful. My
son is very loyal and is reluctant to take a paternity
test. How else can I find out if the boy is really
my grandson?" more...

Reunited?

"My son passed away almost five years ago. Now, some
woman who he dated over 10 years ago contacted me to
say her daughter is my son’s. How do I know this isn’t a case of mistaken
identity? " more...

A
Difficult Situation...

" My son is only 16, and now he has a son of his own. At least, that is
what the mother says. He is not even seeing the mother anymore and has no custodial
rights, but I read that I might be liable for his child support payments. How
do I know the child is actually my grandchild?" more...
